This week, PEOPLE looks in-depth at the July 20 massacre in Colorado, where James E. Holmes, a former neuroscience Ph.D. student at the University of Colorado, allegedly killed 12 and wounded 58 in one of the worst mass shootings in U.S. history.

In these moments of unspeakable terror emerged acts of extraordinary love and courage. Like Teves, two other men, Matt McQuinn, 27, and Jon Blunk, 26, also died as they took bullets for girlfriends.

And there was Prodeo Patria, 14, who despite a bullet in the back helped a wounded man to safety, and is expected to make a full recovery.
